Pros: Great sound
Cons: Uncomfortable and high fatigue
I've owned E2cs then e4cs, then E500's (Se530's), and then moved to UE-11's. I have to say I was unhappy with the sound moving up from my E500's. They were clearly better, but not as much better as I hoped. The UE-11's had a sharper sound to them and I guess I like the warmer sound signature if that means anything. But after listening for a while and trying the E500's again, I couldn't listen to them. Regardless of how I liked the type of signature, the UE-11's were just that much better.
I'd say they're worth the price for sure but definitely not a value headphone.
